6 Ciaiins.

Among the principal objects which the present invention has in view are: To provide an apparatus having means thereon to eliminate the bulging or overlapping portion of material of the 5 corner of a garment and the like; to provide means which will push inwardly the projecting end of a corner of a garment and the like; to enable the pointe-:l corner of a collar to assume a uniform thickness and neatness in appearance; to apply heat to the garment and the like simultaneously with the performance of pushing the projecting end inwardly; and to secure simplicity of construction and operation.

As seen in the drawing, attention is called to the fact that we utilize an apparatus having a standard i5 terminating in a head i8 providing for a vertical slideway il for a plunger i3. The standard furthermore provides a bed i9 positioned below and away from the plunger and adapted to support a forming die 2t, and the plunger i8 carries a pressure die 2l for exerting pressure on the forming die with a garment or the like in place thereon. Operation of the pressure die 2| is obtained by any suitable means (not shown) but conveniently by employment of the means as illustrated in Patent No. 1,934,209 of November '7, 1933. However, such a means may conveniently 45 be connected to a second class lever 22, an intermediate part of which engages the upper end of the plunger I8. One end of this lever may have suitably connected to it, a link 23, by which power is applied, Whereas the other end is fulcrumed as at 24 in a bracket 25 forming part of the head of the apparatus. Preferably lever 22 provides a long arm between the plunger i8 and the connection of the link 23, and provides a short arm between the plunger and the iulcrum 24, so that a moderate pressure exerted by the operator may apply a considerable pressure to the plunger and the pressure die 2! and the forming die 2l). The lower end of link 23 is shown pivoted in a firstclass lever 26 pivoted at 2l and forming part of the power applying means to the treadle (not shown) in accordance with the illustration of Patent Number 1,934,209 aforesaid.

Preferably the forming die 2% is composed of a relatively fixed die section 2B secured as by bolts 29 to the bed i9 and providing a forward face 36 against which the end edge of a collar or the like 3i may be brought into engagement while resting flatv/ise on the bed. The said forming die furthermore provides a slidable die section 32 which likewise rests upon the bed and may slide toward and away from the iiXed die section Z8 normal to the said face Sli. The slidable die section has an end iace 33 normal to the bed and at an acute angle with respect to face Sli corresponding to the desired angle of the intersecting edges of the garment or collar being formed.

lin order to slide this slidable die section 32, the same is shown as having a guiding tongue 34 passing through a corresponding slot in the fixed die section 2?. tioned within a suitable socket, a part it of which is within the slidable die section and a part 3l of which is within the iiXed die section, said parts of the socket being alined and thereby enabling the spring to be positioned therein and force the slidable die section normally away from the xed die section.

A suitable cam is provided to counteract the spring action and move the slidable die section 32 toward the Xed die section 28. shown, one example of such a cam comprises a stem i223 slidable axially parallel to the direction oi movement of the plunger i3. Said stein passes vertically through the iiXed die section, the tongue of the slidable die section and through the bed iii. The p-art of the stem which passes through these several elements when in normal position, is of reduced diameter thereby providing a shank 39 loosely traversing said elements and forming a stop to limit outward movement of the slidable die section as clearly shown in Figure 4.

As the stem 38 is lowered, a tapered enlargement et thereof enters the several holes in the xed die section 2S, slidable die section 32, and bed lil, causing said holes to become axially coincident by virtue of the enlargement it tapering to a full diameter of the stem equal to the diameter of the holes. The slidable die section is accordingly moved rearwardly. This move- A compression spring 35 is posi- As here 3 ment is preferably obtained by depression of the same treadle which operates the plunger I8, and as here shown, the lower end of stem 38 extends laterally as at 4l and is engaged in the end of first-class lever 26. This construction is illustrative of any suitable means for securing simultaneous operation of the slidable die section and the pressure die 2l. It may further be noted that the upper end of the stem 38 may be steadied and guided by passing through a bracket 42 fixed upon the fixed die section 28.

'Ihe sloping face 33 of the slidable die section 32 next the corner thereof toward the fixed die section 28 is provided with a protruding lip 43, said lip being flatwise with respect to the bed I9 and slightly elevated above the same to permit a folded thickness of the garment material to enter thereunder.

It is very usual, in formation of acute-angle corners in garments for the hem or fold to present an undesired protrusion of the material, as shown in Fig. 5, and in operation of the apparatus above described, that protruding portion of material is engaged by the lip 43, and when the lip is slid, is thereby forced inwardly of the edge of the garment, as shown in Figure 6. When once forced in, this corner of the material remains tucked in, particularly since the pressure die 2l is also functioning, preferably with a simultaneous application of heat, upon the corner of the garment. The pressure die 2| is, however, notched, as at 44 so as not to overlie the tongue but so close thereto as to enable the applied pressure to be effective upon the tucked-in portion of the material.

We claim:

1. An apparatus as characterized comprising a forming die having a xed section and a slidable section, said slidable section having a laterally protruding lip thereon directed toward the Xed section, a compression die, said lip being spaced from the lower face of the slidable section and the compression die having a recess to receive said lip throughout its height, and means for actuating the slidable section of the forming die and causing said lip to approach and effect a pressure toward the fixed section in use.
